Description
New eco-friendly gas mixtures are being searched for use in RPC muon detectors of the CMS experiment at the CERN LHC collider. The search must be complemented by detailed studies of the interactions of candidate ecogases with materials utilized in RPC detectors. The strategy followed is two-fold, namely a static and a dynamic search. The static search is performed by comparing materials properties (by means of SEM-EDS, XPS, XRD, FTIR analyses) before and after exposure to candidate ecogases in standard operating Conditions. The dynamic search consists of sampling and analysis (mass spectrography, F- and Cl- sensors) of candidate ecogases as exhausted by detectors after operation in electric fields and irradiation conditions.
